This Kit is to Replace Existing, or for Applications Utilizing, 4.7" (120mm) Fans

This kit is for replacing old, loud fans or AC fans that lack the quality and control features of DC Fans. These are top-quality, DC (low-voltage) fans with a special magnetic levitation system for quiet and long lasting operation. It is not commonly known that ball bearing and sleeve bearing fans are not intended for vertical mounting which is how most fans in audio video cooling are mounted. The reason is that the fan spindles rest on the bearings quickly wearing them out and creating noise. The Magnetic Levitation system 'floats' the spindle so there is no direct contact between the spindle and the bearings. This accounts for the long lasting, quiet operation and, being low voltage, there are more control options for the fans as well.

The most obvious application for these fans are for use in rack manufacturer's faceplates and fan tops that utilize 4.7" or 120mm fans. This kit will directly fit into the two fan version of those faceplates. If you have the three fan version, use this kit and simply add another fan (FK-120-1) and a short lead y-cable (PA-YC-SL).

Current: 190 milliamps per fan at 12V DC

Installation/Assembly

While some installations may vary, generally you will mount the fans by inserting the rubber mounts into the fan/rack bracket.

Then determine the proper direction of the airflow; there is an arrow on the side of the fan that indicates the direction of the airflow.

Once that is determined, insert the mounts into the mounting holes on the fans and pull the mounts until the 'catch'.

Connect the Short Lead Y-Cable to each fan aligning Tip to + on the connector ends.

Once properly connected, then plug in the power supply to the y-cable, again aligning Tip to + and then plug in the power supply.

Once the fans are on, set the voltage to the desired setting with the primary considerations being noise and effectiveness. Typically the power supplies will be set between 7 and 12V DC.
